Abstract:
Multibeam data were measured during R/V Polarstern cruise ANT-XXII/2 along track lines of approximately 6800 NM total length during transits and the Ice Station POLarstern (ISPOL) experiment. Data were achieved during the transit from Cape Town via Bouvet Island towards Antarctic Peninsula for three weeks, crossing Agulhas Ridge, Agulhas Basin and Mid-Atlantic Ridge, and during the transit to Cape Town via South Georgia for two weeks. During the ISPOL station, data were gained while the vessel was drifting for five weeks anchored to an ice floe in the south-western Weddell Sea, starting at 68°13'S/54°47'W. The multibeam sonar system Hydrosweep DS-2 was operated using 59 beams and 90° aperture angle. The refraction correction was achieved using CTD profiles or utilizing the system's own cross fan calibration. The quality of data might be reduced during bad weather periods or adverse sea ice conditions. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position.

Comment:
The raw multibeam sonar data in SURF format are compressed as TAR archive with GZIP. One dataset contains a measurement period not exceeding eight hours. SURF data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/). The source code for an application programming interface (API) to read and write SURF data is released by the Hydrosweep manufacturer Atlas Hydrographic, Bremen, and published under the GNU GPL.
